Check Digit Verification of cas no
The CAS Registry Mumber 176243-28-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,2,4 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 176243-28:
(8*1)+(7*7)+(6*6)+(5*2)+(4*4)+(3*3)+(2*2)+(1*8)=140
140 % 10 = 0
So 176243-28-0 is a valid CAS Registry Number.
